  • the keys 20 are dynamically-scanned via the input/output ports 14 and 15, and each key output is read by the CPU 11 to determine which keys are depressed.
  • the reservation of TV program recordings can be implemented in accordance with a reservation routine 30 as explained with reference to a flowchart shown in FIG. 3.
  • the program routine 30 is stored in the ROM 12.
  • the VTR adopts the reservation mode for the first timer program recording.
  • the routine 30 starts from the step 31, and stands-by an input representative of a tape speed required in the first timer program recording operation in the succeeding step 32. If a tape speed key 22 of the keys 20 is depressed, data TPSP indicative of a tape speed is written in the area A2 of the first timer program recording areas A1 to A6 of the RAM 13 in the step 33.
  • the routine stands-by an input representative of a day of the week for the first timer program recording. If a day key of the keys 20 is depressed, data DAY indicative of a day of recording is written in the area A3 of the first timer program recording areas A1 to A6 of the RAM 13 in the step 35. Thereafter, in the same way, the routine stands-by inputs successively representative of a recording start time, a recording end time, and a channel in the steps 36, 38, and 41, respectively.

  • the reservation operation of the above-mentioned timer program recording is performed in a conversational manner by the use of the display means 5 or a TV screen when a TV set is turned on. Further, if a clear key among the keys 20 is depressed with the first reservation key 21A, for instance, and maintained in a depressed state, the flag data FLAG at the area A1 corresponding to the first timer program recording is reset to release the reservation of the first timer program recording A.
  • the routine 50 starts, beginning from the step 51, and a reservation counter or event counter ECNT is set to "1" in the succeeding step 52.
  • the values of this counter ECNT are from “1” to "4" corresponding to the first to fourth timer program recordings A to D, respectively.
  • the timer program recording corresponding to the value of the counter ECNT is selected. If ECNT is "1", the data areas A1 to A6 for the first timer program recording A are retrieved to read the flag data FLAG stored in the area A1. This read flag data FLAG is checked in the succeeding step 54.
  • step 54 When the flat data FLAG is set, that is, when the timer program recording has already been reserved, the processing proceeds from the step 54 to the step 55.
  • step 55 since ECNT is "1" and the data areas A1 to A6 have been selected in this case, data DAY and STTM are read from the areas A3 and A4.
  • step 56 data indicative of the present day and time are read from the timer 16, and compared with the data DAY and STTM read in the step 55.
  • both data do not match that is, when the present day and time are different from the read day and time, the processing proceeds from the step 56 to the step 57.
  • step 57 only the counter ECNT is incremented by "1".
  • step 58 the routine asks whether or not the counter ECNT exceeds the maximum value of "4". If ECNT is less than or equal to 4, the processing returns from the step 58 to the step 53.
  • step 54 when the flag data FLAG is reset,i.e. when no timer program recording operation is reserved, the processing proceeds from the step 54 to the step 57.
  • each of the reservations of the first to fourth timer program recordings is checked serially in the steps 51 to 58. And, when a reservation has been made, it is determined whether or not the present time is the corresponding program recording start time.
  • the steps 51 to 59 repeatedly check each reservation of the first and fourth timer program recordings. If a reservation is made, the processing checks whether the time reaches the recording start time.
  • step 61 power is supplied to the receiver circuit 1, the recorder circuit 2 and the tape speed controller 4.
